A grab-bag contains 30 packages worth $.65 each, 10 packages $.60 cents each, and 15 packages worth $.30 each. What is the expected value if you have to pay $.50 to pick one package at random?
Answer:
Expected value of package = $0.04 (Approx.)
Step-by-step explanation:
Given:
30 packages at $0.65 each
10 packages at $0.60 each
15 packages at 0.30 each
Pick up price for random one = $0.50
Find:
Expected value of package
Computation:
Total cost of 30 package = 30 x 0.65
Total cost of 30 package = $19.5
Total cost of 10 package = 10 x 0.60
Total cost of 10 package = $6
Total cost of 15 package = 15 x 0.30
Total cost of 15 package = $4.5
Total cost = 19.5 + 6 + 4.5
Total cost = $30
Cost of random package = 30 / [30+10+15]
Cost of random package = $0.54
Expected value of package = 0.54 - 0.50
Expected value of package = $0.04 (Approx.)

9. The formula V=lwh is the volume formula for a rectangular prism. Find the length (l) of a prism with volume (V) 1200 cm³, width (w) 15 cm, and height (h) 8 cm.
A. 6 cm
B. 8 cm
C. 10 cm
D. 14 cm
please show how you got the answer!
Answer:
C. 10cm
Step-by-step explanation:
First we can rearrange the equation to solve for length (l):
V = lwh
Divide both sides by wh:
l = V/(wh)
Substitute in known values:
l = 1200/(15x8)
l = 1200/120
l = 10cm

The surface area of a cone is determined by the equation SA= a rs + a r2, where r is the radius and s is the slant
height. The functions f(x) and g(x) both model the surface area of a cone. One of the functions represents the
surface area of a cone with a radius of 5 and a slant height of x. The other function represents the surface area of a
cone with a slant height of 5 and a radius of x. Which statement correctly matches the description of the function
with the domain of the function in the context of the problem situation?
The function f(x) models the surface area of a cone with a radius of 5, a slant height of x, and has a domain in
the context situation of x < 5.
® The function f(x) models the surface area of a cone with a radius of 5, a slant height of x, and has a domain in
the context situation of x > 5.
© The function g(x) models the surface area of a cone with a radius of 5, a slant height of x, and has a domain in

y=3(19)-5 y=2(19)+14
Answer:
solution given:
y=3(19)-5=57-5=52
y=2(19)+14=2×19+14=38+14=52
:.
y=52
Answer:
y = 52
Step-by-step explanation:
Order of operation says we must multiply before you subtract or add.
So 3 * 19 = 57 then subtract 5 you get 52.
Next 2 * 19 = 38 then 38 + 14 = 52

if tan27° =k express the following in terms of k
1. sin 27°
Answer:
) ''You need to consider 200^o = 180^o + 20^o , hence you need to use the next formula to evaluate sin 200^o in terms of k:
sin (alpha + beta) = sin alpha*cos beta + sin beta*cos alpha
Plugging alpha = 180^o , beta = 20^o in the formula yields:
sin 200^o = sin (180^o + 20^o) = sin 180^o*cos20^o + sin 20^o*cos 180^o
Plugging sin 180^o = 0 and cos180^o = -1 in the formula yields:
sin 200^o = - sin 20^o = -k''

Determine the quadratic curve of best fit for the data. Then estimate what the value of will be when = −4. {(−3,2), (0,5), (1,7.3), (−1,3.3), (−6,5), (−7,7.3)} Answer choices 4.3 5.3 3.3 2.3
Answer:
The value of 'y' when x = -4 is 2.3
Step-by-step explanation:
Curve of best fit can be found by plotting the points on MS Excel and drawing a curve that goes through the points as shown in the attached graph
The equation that approximate the curve from which the y-value at a x-value of -4 can be estimated is found as follows
The general equation for a quadratic equation is y = a·x² + b·x + c
Therefore, we get;
2 = a·(-3)² + b·(-3) + c
2 = 9·a - 3·b + c
5 = 0·a + 0·b + c
5 = c
7.3 = 1·a + 1·b + c = a + b + 5
7.3 = a + b + 5
2.3 = a + b
2 = 9·a - 3·b + 5
-3 = 9·a - 3·b
Solving gives;
a = 13/40, b = 79/40
The equation of the quadratic curve is therefore;
y = (13/40)·x² + (79/40)·x + 5
When x = -4, we get;
y = (13/40)·(-4)² + (79/40)·(-4) + 5 = 2.3
When x = -4, y = 2.3
Plotting the points on MS Excel we find from the attached graph that the estimated value of 'y' when x = -4 is as calculated (2.3).

Leslie has a watering can that holds 1 liter of water. She uses 250 milliliters of water on each of her plants. How many plants can she water? *remember 1L = 1000 milliliters of water
Answer:
4 plants
Step-by-step explanation:
convert the capacity of the watering can to millimeters
1L = 1000 milliliters
1 x 1000 = 1000 millimeters
Plants that can be watered = capacity of the watering can / amount of water a plant needs
1000 / 250 = 4 plants

0 3x = 9
0 3x = 11
O 11x = 9
0 11x = 1
Answer:
11x=1
Step-by-step explanation:
15x+4=5+3x+1x Bring everything with an x in front of it to the left side
